Early mobilisation following fragility hip fracture surgery: current trends and association with dicharge outcomes in a local tertiary hospital
Introduction: Postoperative day 1 (POD1) mobilisation is a key clinical indicator for the fragility hip fracture surgery population. This study aimed to evaluate the current trends of POD1 mobilisation at our institution; and to review the relationships between early mobilisation and outcomes of early functional recovery, length of stay (LOS) and discharge destination. Methods: In this preliminary observational study, data pertaining to demographics, pre-morbid function, health status, injury and surgical factors, POD1 mobilisation status and clinical outcomes of interest were retrieved from eligible patients. Patients who attained POD1 ambulation formed the “Early Ambulation (EA)” Group while the remaining patients formed the “Delayed Ambulation (DA)” group. Data were analysed for any significant difference between the groups. Results: 115 patients were included in the analysis. The rate of patients achieving at least sitting out of bed on POD1 was 80.0% (92 patients) which was comparable with data available from international hip fracture audit databases. 55 patients (47.8%) formed the EA group and 60 patients (52.5%) formed the DA group. EA group was approximately nine times more likely to achieve independence in ambulation at discharge compared to the DA group (adjusted odds ratio 9.20; 95% Confidence Interval 1.50-56.45; p = 0.016). There were observed trends of shorter LOS and more proportion of home discharge in the EA group compared to DA group (p > 0.05). Conclusion: This is the first local study to offer benchmark of the POD1 mobilisation status for this population. Patients who attained POD1 ambulation had better early functional recovery.
